Sansevieria Plant Named &#39;OSV Sans 011&#39;

ABSTRACT

A new and distinct  Sansevieria  plant having leaves with an intense, dark green central portion and a yellow lateral border. One or more of yellow-green veined stripes and thin yellow stripes may also be present.

CROSS REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of priority from U.S. Provisional Patent Application No. 63/204,558, filed Oct. 8, 2020, which is incorporated herein by reference in its entirety.

Botanical classification: Dracaena sansevieria.

Varietal denomination: ‘OSV Sans 011’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Sansevieria plant, botanically known as Dracaena sansevieria, having the varietal name of ‘OSV Sans 011’ and commercially referred to as “Black Star”. ‘OSV Sans 011’ is the result of a cross conducted in Costa Rica in a planned breeding program by the inventor. The new variety was selected and first asexually reproduced by cuttings in Costa Rica. ‘OSV Sans 011’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

When compared to Sansevieria variety named ‘OSV Sans 004’ (U.S. Plant patent application Ser. No. ______), the new variety exhibits a similar rosette leaf formation, gladiate leaf shape, and leaves growing upward and then curving outward. However, ‘OSV Sans 011’ differs from ‘OSV Sans 004’ in having a solid leaf coloration with no speckling and thick margins. Further, the following characteristics distinguish ‘OSV Sans 011’ from other Sansevieria varieties known to the breeder:

-   -   Rosette leaf formation;     -   Prominent leaf margins; and     -   Solid leaf coloration with no speckling.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing taken at approximately 18 weeks of age illustrates the new variety, with the colors being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety at approximately 2 years of age. The data which defines these characteristics was collected in a greenhouse in September of 2021 in Winter Garden, Fla. Plants of the new variety were grown under 2,000 foot candles of artificial light in 15 cm pots in a climate-controlled greenhouse in Winter Garden, Fla. having 86% relative humidity and an average temperature of 28° C. Color references are primarily to the Munsell Plant Tissue Color Book, 2019 publication, except where general color terms are used.
